Photocatalytic Reaction of Ethanol over Titanium Diselenide

Article abstract of DOI:10.1246/bcsj.66.1038

A suspension of TiSe2 in ethanol was illuminated with ultraviolet light in an atmosphere of Ar, air, or O2 at 298 K.The main products were acetaldehyde, acetaldehyde diethyl acetal (acetal), acetic acid, water, hydrogen, ethylene, methane, and carbon dioxide.Each yield of the products under air or O2 was higher than under Ar, except for that of hydrogen and ethylene.Platinum under an O2 atmosphere exerted its effect for producing CH3COOH, acetal, CO2, CH3CHO, CH4, and H2O, while under Ar it contributed to generating CO2, CH4, and H2.No effect of Pt was observed for generating C2H4 under either an atmosphere of Ar or O2.
